【摘要】：本文針對(duì)姬塬油田樊學(xué)區(qū)域開采現(xiàn)狀及存在的問題,對(duì)區(qū)塊的開發(fā)方式、開發(fā)層系、井網(wǎng)部署、壓力系統(tǒng)及技術(shù)政策等進(jìn)行分析、論證,提出適合本區(qū)塊的注水開發(fā)方案。結(jié)合靜、動(dòng)態(tài)的資料,建立數(shù)值概念模型,對(duì)裂縫方向與注采井網(wǎng)的適應(yīng)性及井網(wǎng)部署進(jìn)行數(shù)模計(jì)算。分別將裂縫的方向與注采井排的夾角設(shè)置為0°、45°、90°進(jìn)行數(shù)值模擬,模擬結(jié)果表明,當(dāng)夾角為0°時(shí)的開發(fā)效果較好。在井網(wǎng)優(yōu)選方面,對(duì)6種井網(wǎng)類型分別進(jìn)行了數(shù)值模擬計(jì)算,結(jié)合油藏工程方法與數(shù)值模擬的結(jié)果,綜合表明初期選用菱形反九點(diǎn)法較好。確定井排方向?yàn)楸睎|55o,裂縫方向上的注水井距為240m,排距為80m。文中綜合多種方法確定單井產(chǎn)能為0.41t/d,并運(yùn)用經(jīng)驗(yàn)公式計(jì)算單井日注水量為3.1m3/d。
[Abstract]:In view of the present situation and existing problems of Fanxue area in Jiyuan Oilfield, this paper analyzes the development mode, development layer system, well pattern deployment, pressure system and technical policy of the block, demonstrates and puts forward a water injection development scheme suitable for this block. Based on the static and dynamic data, a numerical conceptual model is established to calculate the adaptability of fracture direction and injection-production well pattern and the deployment of well pattern. The angle between fracture direction and injection-production well row is set to 0 擄, 45 擄and 90 擄respectively. The simulation results show that the development effect is better when the angle is 0 擄. In the aspect of well pattern optimization, the numerical simulation calculation of six types of well pattern is carried out respectively. combined with the results of reservoir engineering method and numerical simulation, the comprehensive results show that the rhomboid reverse nine point method is better in the initial stage. The well row direction is determined to be 55o in the northeast, the injection well spacing in the fracture direction is 240m, and the row spacing is 80m. In this paper, the productivity of a single well is determined to be 0.41t / d by using various methods, and the daily water injection volume of a single well is calculated to be 3.1m3 / d by using the empirical formula.
