【摘要】：油田目前已進(jìn)入高含水后期開發(fā)階段,每年新增產(chǎn)能及可采儲(chǔ)量逐漸減少,尋找新增可采儲(chǔ)量緩解儲(chǔ)采失衡矛盾是一項(xiàng)很緊迫的任務(wù),而窿15區(qū)塊儲(chǔ)層是油田高含水開發(fā)后期接替潛力資源。因此需要準(zhǔn)確的計(jì)窿15區(qū)塊儲(chǔ)量,為合理開發(fā)窿15區(qū)塊油層提供重要依據(jù)。本文研究了窿15區(qū)塊油層的構(gòu)造特征、儲(chǔ)層特征、油藏特征。根據(jù)沉積特征和電測曲線把窿15區(qū)塊油層劃分為三個(gè)計(jì)算單元。通過巖心、測井曲線及各種分析化驗(yàn)資料對(duì)油層的沉積相進(jìn)行了詳細(xì)描述。對(duì)窿15區(qū)塊油層的油藏類型、壓力與溫度、流體性質(zhì)、油層產(chǎn)能情況進(jìn)行了研究。本文對(duì)地質(zhì)儲(chǔ)量的計(jì)算參數(shù)進(jìn)行了確定。依據(jù)油藏剖面圖和有效厚度發(fā)育情況圈定了含氣、含油面積。通過對(duì)儲(chǔ)層四性關(guān)系、有效厚度物性標(biāo)準(zhǔn)、有效厚度電性標(biāo)準(zhǔn)的研究,確定了有效厚度解釋標(biāo)準(zhǔn)。利用密閉取心資料、高壓物性資料、原油分析資料確定了有效孔隙度、原始含油(氣)飽和度、體積系數(shù)、原始?xì)庥捅�、原油密度等參�?shù)。采用容積法計(jì)算了窿15區(qū)塊天然氣地質(zhì)儲(chǔ)量和石油地質(zhì)儲(chǔ)量。
[Abstract]:At present, the oilfield has entered the stage of high water cut, and the new production capacity and recoverable reserves are gradually decreasing every year. It is an urgent task to find new recoverable reserves to alleviate the imbalance between storage and production.The reservoir in Block No. 15 is a potential resource in the later stage of high water cut development.Therefore, it is necessary to provide an important basis for the rational development of reservoir in Block No. 15.In this paper, the structural characteristics, reservoir characteristics and reservoir characteristics of reservoir in Block No. 15 are studied.According to the sedimentary characteristics and the electric survey curve, the reservoir of Block 15 is divided into three calculation units.The sedimentary facies of the reservoir are described in detail by means of core, log curves and various analytical and laboratory data.The reservoir type, pressure and temperature, fluid properties and productivity of reservoir are studied.The calculation parameters of geological reserves are determined in this paper.The gas-bearing and oil-bearing areas are delineated according to the reservoir profile and the development of effective thickness.The effective thickness interpretation criteria are determined through the study of the four properties of reservoir, the physical property standard of effective thickness and the standard of electrical property of effective thickness.Using closed coring data, high pressure physical property data and crude oil analysis data, the effective porosity, original oil (gas) saturation, volume coefficient, original gas-oil ratio, crude oil density and other parameters are determined.The geological reserves of natural gas and petroleum geology in Block No. 15 are calculated by volume method.
