【摘要】：隨著三次石油開采技術(shù)的變革,傳統(tǒng)的注水驅(qū)油技術(shù)在開采剩余油量不足,高滲透層的采集中,逐漸被注聚驅(qū)油技術(shù)所取代。由于層間矛盾突出,開發(fā)了分層注聚工藝,進(jìn)一步提高聚驅(qū)采收率。分層注聚技術(shù)有效的解決了多層間采集量不一致的問題。聚合物溶液是非牛頓假塑性流體,在通過配注器時會受到機(jī)械剪切的作用,粘度降低,影響出油率。因此閥芯的結(jié)構(gòu)設(shè)計(jì),需要保持聚合物溶液的粘度。分注井?dāng)?shù)和層數(shù)的不斷增加,測試工作量逐年增加。為了提高聚合物驅(qū)油開采率,解決現(xiàn)在分層注聚的一些弊端,開發(fā)出一套適合挖潛剩余油的有效注聚工藝。本文正是基于解決這一三次采油中面臨的問題而開展研究工作的,研制預(yù)置電纜式智能分成注聚測調(diào)工藝,解決了注聚開采中,由于機(jī)械剪切作用,使得聚合物粘度損失大,不能夠連續(xù)調(diào)節(jié)水嘴開度的問題,該工藝實(shí)現(xiàn)了:多層段同步測調(diào),上位機(jī)實(shí)時監(jiān)測,實(shí)時控制聚合物流量,連續(xù)調(diào)節(jié)的目的。不僅滿足了聚合物采油機(jī)械本體的要求,又將電控式采油應(yīng)用到聚驅(qū)采油中。提高了監(jiān)測精度和效率,為三次采油自動化開采提供技術(shù)支持。根據(jù)聚合物驅(qū)油技術(shù)的要求,設(shè)計(jì)了聚驅(qū)電控式智能配注器分層注聚系統(tǒng)的注聚管柱,智能化電動測調(diào)儀。將stm32作為核心控制器,包括:井下連續(xù)可調(diào)的直線電機(jī)、井下流量、壓力、溫度采集模塊,ST編解碼電路等。自動化配注應(yīng)用到石油開采中,上位機(jī)采用VS2008開發(fā)環(huán)境,石油工作人員可以在測調(diào)工作室完成數(shù)據(jù)的交換、定時采集、實(shí)時監(jiān)控,并為后續(xù)石油驅(qū)塊化發(fā)展提供了先發(fā)條件。
[Abstract]:With the development of tertiary oil recovery technology, the traditional waterflooding technology is gradually replaced by polymer flooding technology in the production of low residual oil and high permeability reservoir. Because of the outstanding interlayer contradiction, the technology of stratified polymer injection is developed to further improve the recovery factor of polymer flooding. Stratified polymer injection technology effectively solves the problem of multi-layer data collection inconsistency. Polymer solution is a non-Newtonian pseudoplastic fluid, which will be subjected to mechanical shear when passing through the injector, and the viscosity will be reduced, which will affect the oil yield. Therefore, the structural design of the valve core, need to maintain the viscosity of polymer solution. With the increasing number of injection wells and layers, the test work is increasing year by year. In order to improve the oil recovery rate of polymer flooding and solve some disadvantages of stratified polymer injection, an effective polymer injection process suitable for tapping potential remaining oil is developed. In this paper, the research work is carried out to solve the problems in the third oil recovery, and a preset cable intelligent split polymer injection test and adjustment process is developed, which solves the problem of polymer viscosity loss due to mechanical shear in polymer injection extraction. The process can not continuously adjust the opening of water nozzle. The purpose of this process is: multilayer synchronous measurement and adjustment, real time monitoring of upper computer, real time control of polymer flow rate and continuous adjustment. It not only meets the requirements of polymer oil recovery machinery, but also applies electronic control oil recovery to polymer flooding. It improves the monitoring accuracy and efficiency, and provides technical support for the automatic production of tertiary oil production. According to the requirements of polymer flooding technology, a polymer injection pipe string and an intelligent electric measuring and adjusting instrument are designed for the polymer flooding intelligent injector. Stm32 is used as the core controller, including: downhole continuous adjustable linear motor, downhole flow rate, pressure, temperature acquisition module and St codec circuit. In the application of automatic injection allocation to oil production, the host computer adopts VS2008 development environment, oil workers can complete data exchange, timing acquisition, real-time monitoring in the survey and adjustment studio, and provide the first sending condition for the subsequent development of oil flooding block.
