Description
Technical field
The present invention relates to oil recovery technique field, oil field, particularly a kind of reducing crude oil viscosity treatment agent is the ultra emulsifying and viscosity-reducing agent for condensed oil of a kind of anti-salt temperature-resistant type.
Background technology
Viscous crude is the important component part of world petroleum resource.The reserves of China's viscous crude are abundant, and explored prospective oil is about 5,000,000,000 tons, and wherein viscous crude is 1,400,000,000 tons, account for the nearly 30% of total prospective oil, are the world the fourth-largest viscous crude producing countries after the U.S., Canada and Venezuela.Along with the intensification of petroleum resources exploitation degree and the minimizing of world petroleum resource reserves, the exploitation utilization technology of viscous crude more and more comes into one's own.
Light constituent content is low in the viscous crude; Bituminous matter and gum level are higher, and straight chain hydrocarbon content is few, cause most of viscous crude to have HV and highdensity characteristic; Therefore be prone in the viscous oil recovery process that the oil pumper load is big, current consumption is big, mechanical accident is frequent, the problems such as back pressure height of surface pipeline; Bring very big difficulty for the safety in production of heavy oil wells, for guaranteeing the safety in production of heavy oil wells, research reducing thick oil viscosity production technique is a task that urgency is to be solved.The key of heavy oil wells safety in production is the reduction viscosity of thickened oil, improves its flowability, to reduce the flow path resistance of viscous crude in the lifting process, reduces the oil pumper load.
At present, in the viscous oil recovery process, viscosity reducing process commonly used both at home and abroad has heating method, mixes the thin oil method, viscous crude upgrading viscosity reduction and chemical agent viscosity reduction method.Wherein the chemical viscosity reduction method comprises oil soluble viscosity reducing process and reducing viscosity by emulsifying method.Field conduct is workable, technology is versatile and flexible because the reducing viscosity by emulsifying technology has, to characteristics such as environmental compatibility are strong, therefore be considered to a good reducing thick oil viscosity technology of application prospect.
The thick-oil emulsified adhesive-reducing production technique starts from the sixties in 20th century, and Simon and Poynter inject tensio-active agent in pit shaft, makes highly viscous crude be transformed into O/W type milk sap by w/o type milk sap, and from improving oil-production efficiency.
Thick-oil emulsified adhesive-reducing is with the certain density water-soluble viscosity-depression agent aqueous solution, under certain condition with the viscous crude thorough mixing; Because of the hydrophilic group surfactivity in the water-soluble viscosity-depression agent is very strong, can substitute w/o type naturally occurring emulsifying agent on the water-oil interface (like colloid, bituminous matter) and formation oriented adsorption layer; Adsorption layer will change molecular interaction and surperficial transmittance process consumingly, and high viscosity heavy oil is scattered in the active water with the oil droplet form, form LV O/W type milk sap; Make oil-oily interface become oil-water interface; Thereby viscous crude molecule directly contact and collision have been avoided; Finally cause milk sap viscosity and viscosity of thickened oil relation little, but relevant with water as external phase, so the viscosity of O/W milk sap reduces greatly; And water ratio is high more, and crude oil emulsion viscosity is more little.
Summary of the invention
The objective of the invention is: provide a kind of anti-salt temperature-resistant type ultra emulsifying and viscosity-reducing agent for condensed oil, can carry out reducing viscosity by emulsifying to viscous crude, and anti-salt property reaches 24 * 10
