【摘要】：化子坪黑山梁油區(qū)自2004年投產(chǎn)至今,已進(jìn)入穩(wěn)定開發(fā)階段。研究儲(chǔ)層特征與油藏特征,是油區(qū)進(jìn)行注水開發(fā)的基礎(chǔ)；研究目前引起剩余油形成,控制其分布規(guī)律的因素,是提高油區(qū)采收率的關(guān)鍵。本研究綜合運(yùn)用地質(zhì)、測井、生產(chǎn)靜態(tài)、動(dòng)態(tài)資料以及相鄰區(qū)塊前入研究成果,以沉積巖石學(xué)、石油地質(zhì)學(xué)、油層物理、儲(chǔ)層地質(zhì)學(xué)、滲流力學(xué)為理論依據(jù),開展油藏特征、剩余油分布類型及注水開發(fā)相應(yīng)調(diào)整措施研究,為黑山梁油區(qū)實(shí)現(xiàn)增產(chǎn)增效,提高油田采收率的目提供理論依據(jù)。黑山梁油區(qū)主力產(chǎn)油層位為長62-1、長62-2、長63小層,屬三角洲前緣亞相沉積。根據(jù)盆地?zé)N源巖性質(zhì)、延長組在各時(shí)期沉降中心變化規(guī)律所確定的構(gòu)造格局今古相似區(qū)、結(jié)合盆地基底斷裂與裂縫形成的優(yōu)勢運(yùn)移通道方向,可以確定黑山梁油區(qū)油氣充注方向?yàn)楸蔽鳌蠔|向。油藏展布主要受砂體巖性、運(yùn)移距離(與生烴凹陷距離)、沉積微相、構(gòu)造背景、砂巖上傾方向封隔作用的影響,屬構(gòu)造、巖性同時(shí)控制的巖性油藏。垂向上主要發(fā)育三套油層,但由于沉積微相變化頻繁,薄油層較發(fā)育。油藏主要靠彈性—溶解氣驅(qū),天然能量不足,因此需要進(jìn)行注水開發(fā)。依據(jù)研究區(qū)油藏及儲(chǔ)層巖石學(xué)特征,結(jié)合生產(chǎn)現(xiàn)狀,劃分剩余油注水受效區(qū)域,分析剩余油主要形成的原因有：儲(chǔ)層微構(gòu)造、砂體上傾尖滅、儲(chǔ)層非均質(zhì)性(包括儲(chǔ)層層內(nèi)非均質(zhì)性、層間非均質(zhì)性和平面非均質(zhì)性)、開發(fā)策略及生產(chǎn)工藝。針對(duì)研究區(qū)剩余油分布特點(diǎn),從垂向和平面兩方面入手,提出相應(yīng)的井網(wǎng)布局、油井轉(zhuǎn)注、調(diào)整工藝措施的策略。
[Abstract]:Huaziping heishanliang area has been put into operation since 2004, has entered a stable development stage. The study of reservoir characteristics and reservoir characteristics, is the basis for water development in the present research; residual oil formation causes, factors controlling the distribution, is the key to improve oil recovery. In this study the integrated use of geological, logging, production the static and dynamic data and the adjacent blocks before entering the research results in sedimentary petrology, petroleum geology, reservoir geology, reservoir physics, fluid mechanics theory, reservoir characteristics, residual type and water injection development adjustment measures of oil distribution, for the heishanliang area to achieve production efficiency, and provide a theoretical basis for enhancing oil recovery rate the purpose of the heishanliang area. The main production horizon is long 62-1, long 62-2, 63 small layer, belongs to delta front subfacies. According to the characteristics of source rocks in the basin, the extension of group in each period of settlement Structure changes of the ancient center of similar area, combined with the advantages of migration direction of the formation of basement fractures and cracks, can determine the oil and gas filling direction heishanliang oilfield as NW se trending. Reservoir distribution is mainly affected by the lithologic, migration distance (and hydrocarbon generating sag, sedimentary microfacies, distance) tectonic background, sandstone updip sealing effect, vibration effect belongs to the tectonic, lithologic reservoir lithology and vertical control. There are three sets of reservoir sedimentary microfacies, but due to the frequent change of thin oil reservoir is developed. The reservoir mainly depends on the elasticity of dissolved gas flooding, lack of natural energy, so the need for water development. On the basis of research on petrologic characteristics of reservoir and reservoir, combined with production status, divide the remaining oil by water injection effect, analysis of the causes of residual oil formation are: reservoir structure, sand Piching, reservoir heterogeneity (including Inlayer heterogeneity, interlayer heterogeneity and plane heterogeneity), development strategy and production process. According to the characteristics of the distribution of remaining oil in the study area, from the two aspects of vertical and horizontal wells, proposed network layout, the corresponding converted injection wells and adjusting the process measures.
