Auxiliary Cement Equipment From Serva China

AUXILIARY CEMENTING EQUIPMENT
To satisfy the requirements of oilfield cementing job, the auxiliary equipments are developed according to different cementing techniques, including upstream water supply, cement supply, air supply, adding and mixing of chemicals, downstream job data acquisition, cementing instrument van/instrument skid, etc.

Offshore continuous liquid additive skid

1.Overview
The LAS system is designed to continuously add liquid additives into the slurry during the process of offshore or inland oilfield cement jobs. It greatly simplifies the storage of base cement materials. The system makes it possible to satisfy various cement jobs that havedifferent technical requirements with only one grade of cement material stored.
The LAS system is a more scientific and rational solution to liquid additive addition. In addition, the LAS system is the most common practice introduced by many the major cementing companies.
For a specific cement job, first input into the programmable controller parameters for additive and its proportion. The Serva LAS system automatically delivers the desired amount of each kind of additive in accordance with the flow rate detected from the cement pumpingskid (truck). It is more convenient and less costly than the regular practice because the system ensures the slurry is strictly made up according to the real amount required for a cement job. It reduces the amount of liquid additives usage and also helps protect theenvironment (less disposal of unused material).

Remote wireless cementing data acquisition system

The remote wireless cementing data acquisition system is composed of wireless data transmitting terminal and receiving terminal. The wireless data acquisition software equipped in wireless data transmitting terminal can be used with SJS newly devel­oped and researched auto mixing control system ACM-IV.1. The related operation information of cementing job data (such as water flow, cement valve position, water valve position, slurry density, plunger pump pressure, discharge rate, etc.) are transmitted to the receiver of wireless data receiving box via wireless communication method, and then printed out in the form of report or curve via wireless data acquisi­tion software installed in laptop.
Wireless data acquisition adopts wireless series port modem for data transmission, avoids the limitation of wired connections and improves the reliability of data transmission and safety of operator. The acquisition system has the features of small volume, easy operation, stable performance, high anti-interference, can ensure long distance signal transmission and applicable for operation in oil field.
Wireless data communication can also adopt Internet for data transmission. The field acquisition terminal transmits job data to remote cementing data server; the server receives real-time job data and stores them into database. Users can monitor real­time job data and check history job data by visiting cementing data server website. If the laptop supports wireless Internet access (equipped with wireless card, etc.), users can monitor            job data at any regions with network to realize the
remote mobile monitoring.
Internet data communication also adopts BGAN service to realize global satellite communication via maritime satellite, which is convenient for users checking job data through Internet at remote areas where mobile signals can't cover.
Remote wireless cementing data acquisition system is composed of wireless data transmitting terminal and wireless data receiving terminal. The system can realize wireless transmitting and receiv­ing of remote cementing & mixing job data, which has the features of remote communication, stable performance, high anti-interference and applicable for operation in oil field. Cementing instrument van

1.Overview
Cementing instrument van is applicable for cementing job on land oilfield. It can realize monitoring the whole process of cementing job; centralized control multiple auto mixing equipments; can design the cementing job; can not only real time acquire, display and record the data of whole process cementing, but also process, record and store the job data and then print out job data and curve. The cementing instrument van is composed of chassis, cabin, damping system, power system, communication system, air conditioning system, computer data acquisition system, well head data wireless & wire transmitting device, wire data acquisition system and auto mixing control system, cementing design software, etc. It can work for long time under the environment of -20°C~50°C.
The main technical parameters and performance, such as carborne performance, load distribution and non-grade highway property of equipment, all meet national industry standard and legislation requirement
