摘要:
渤海LD油田为中深层厚层块状特稠油油藏,是国内海上迄今为止发现的原油粘度最大的稠油油田,蒸汽辅助重力泄油(SAGD)技术是开发此类油田的有效手段。通过三维物理模拟分析了LD油田SAGD开发的可行性,认为该油田先吞吐降压,再转SAGD的开发方式能够取得较好的开发效果。经过3个吞吐轮次,油藏压力由6 MPa降至3 MPa,井间温度升至85 ℃,达到转SAGD时机。蒸汽吞吐降压阶段采出程度5.75%,SAGD过程中汽腔上升到顶层时采出程度13.5%,汽腔水平扩展阶段结束时采出程度30.5%,至瞬时油汽比降至0.
Abstract:
Bohai LD Oilfield is a thick massive extra heavy oil reservoir in mid-deep strata.So far it is the largest viscosity of the oil field found in the domestic offshore,and the steam assisted gravity drainage(SAGD)technology is an effective way to develop this kind of oilfield.The feasibility of SAGD development in LD Oilfield is analyzed by means of three-dimensional physical simulation.It is concluded that the oilfield can obtain better development effect by the first step of steam huff and puff to reduce formation pressure and the next step of SAGD development.After 3 rounds of stimulation,the reservoir pressure was decreased from 6 MPa to 3 MPa,the temperature between the wells was increased to 85 degrees,reaching the timing of SAGD production.The recovery rate of the steam stimulation stage was 5.75%.During SAGD,when the steam chamber rose to the top of the reservoir,the recovery rate was 13.5%.By the end of horizontal expansion stage of the steam chamber,the recovery rate was 30.5%.When the instantaneous oil steam ratio was reduced to 0.1,the final recovery rate was 54.7%.Through numerical simulation and inversion,the injection and production parameters were optimized.The optimization of instantaneous steam injection volume was 363.7 m3/d,the production-injection ratio was more than 1.2,it was changed to SAGD production after 3 rounds of steam stimulation,and the distance between injection and production well was 6.5 m.
