【摘要】：油氣源斷裂是油氣垂向運(yùn)移的主要通道,其輸導(dǎo)能力受自身的活動(dòng)性所制約。只有在成藏關(guān)鍵時(shí)期活動(dòng),溝通有效的烴源巖及儲(chǔ)層,且具有頂封能力的斷裂,才能為油氣的運(yùn)移提供優(yōu)勢(shì)輸導(dǎo)通道,使成熟烴源巖排出的大量油氣能夠向儲(chǔ)層中運(yùn)聚成藏。近年來(lái),越來(lái)越多的勘探證實(shí)油氣并非是圍繞著整條油氣源斷裂分布,而是集中分布在斷裂走向拐點(diǎn)、斷裂交匯部位及斷裂末端等變換構(gòu)造發(fā)育的部位。變換構(gòu)造發(fā)育的部位應(yīng)力集中,易引發(fā)地震,地震活動(dòng)會(huì)進(jìn)一步激發(fā)流體運(yùn)移。結(jié)合目前變換構(gòu)造發(fā)育位置通常與油氣分布關(guān)系密切這一現(xiàn)象,認(rèn)為油氣源斷裂上變換構(gòu)造發(fā)育的部位為油氣的優(yōu)勢(shì)運(yùn)移通道。以塔里木盆地庫(kù)車(chē)坳陷克拉蘇構(gòu)造帶為例,從變換構(gòu)造的形成機(jī)制出發(fā),結(jié)合坳陷內(nèi)斷裂的幾何學(xué)特征及分布規(guī)律,將變換構(gòu)造劃分為4種類(lèi)型:趨近型、轉(zhuǎn)換斜坡型、傳遞斷層型和撕裂斷層型。在厘定油氣源斷裂的基礎(chǔ)上,利用油氣源斷裂的斷距-距離曲線等方法識(shí)別斷裂上變換構(gòu)造發(fā)育的部位,并結(jié)合油氣藏分布規(guī)律,分析油氣源斷裂變換構(gòu)造對(duì)油氣成藏的控制作用。
[Abstract]:Hydrocarbon source fault is the main channel of oil and gas vertical migration, and its transport ability is restricted by its own activity.Only when the hydrocarbon source rocks and reservoirs are communicated effectively during the key period of reservoir formation, and the faults with top sealing ability can provide an advantageous channel for oil and gas migration and migration, so that a large amount of oil and gas discharged from mature source rocks can be transported to the reservoir to form reservoirs.In recent years, more and more exploration has proved that oil and gas are not distributed around the whole hydrocarbon source fault, but are concentrated in the fault strike inflexion, the fault intersection and the fault end, etc.The stress concentration in the transposed structure is easy to cause earthquakes, and seismic activity will further stimulate fluid migration.In view of the fact that the location of tectonic development is usually closely related to the distribution of oil and gas, it is considered that the position where the transformed structure develops on the source fault of oil and gas is the dominant migration channel of oil and gas.Taking the Klassou structural belt of Kuqa depression in Tarim Basin as an example, based on the formation mechanism of the transformation structure, combined with the geometric characteristics and distribution law of the internal faults in the depression, the transformation structures are divided into four types: approaching type, transforming slope type, and so on.Transfer fault and tear fault.On the basis of determining oil and gas source faults, the fault distance curves of oil and gas source faults are used to identify the location of the structural changes on the faults, and the distribution law of oil and gas reservoirs is combined.The controlling effect of oil and gas source fault transformation structure on oil and gas accumulation is analyzed.
